Ozone Radon 5K Review

Ozone Radon 5K Review

The Ozone Radon 5K retails for £40.98, which is a fairly reasonable price for a gaming mouse these days. However, it has an odd size and shape. For starters, it’s far too tall for its relatively short length. This means that its peak, which rises just behind your knuckles, digs into your palm in an unpleasant way. In fact, it pushes your hand into an arched position and places strain on your wrist.

This means that the Radon 5K doesn’t fit into your hand naturally, so you’re left feeling that you aren’t in complete control of it. Perhaps the worst aspect of the design is the lack of support it provides for your little finger and ring finger, though. In fact, the right edge of the mouse actually bends in under itself as it meets the desk, so our little finger was constantly being trapped between the mouse and the desk.

Two thumb buttons are located along the join between the side and upper surfaces of the mouse; the former is covered in an unpleasant ridged rubber grip that feels like the tyre of a mountain bike. Thanks to the awkward shape of the mouse, the thumb buttons are positioned close to your thumb. However, they don’t feel very solidly constructed. The other buttons feel much firmer and include a dpi sensitivity rocker switch behind the scroll wheel.

Thankfully, weight isn’t as much of an issue as it is with the Roccat Kone+. The Radon 5K is very light, yet feels solid, aside from the thumb buttons. Thanks to large Teflon feet that sit between the mouse and your desk or mouse pad, it moves almost effortlessly too.

The box includes some optional weights as well, so if the mouse feels as if it’s been on too much of a diet, you can adjust its weight. The weights even have their own little bag, as does the mouse, so both can be protected from pizza and Coke spills when going to and from LAN parties.

Meanwhile, the Radon 5K’s software has all the basics. For adjustment, you’re able to tweak the sensitivity between 100dpi and 5,600dpi, with the level of sensitivity indicated by lights above the thumb buttons. You can also create profiles and alter the USB polling rate to either 125Hz, 250Hz, 500Hz or 1KHz.

In games, the Radon 5K was fairly responsive and precise. However, it isn’t very comfortable thanks to its bulbous shape that left our ring finger and little finger feeling very insecure. As such, they spent more time dragging on the desk than anything else. The Radon 5K also seems to be slightly biased on the X axis. We're not entirely sure whether this is due to the shape of the mouse or the sensor, but there’s little you can do without a separate axis adjustment in the configuration.

The Radon 5K isn’t massively flawed, but it’s in no way as rounded and pleasant to use as the Razer Imperator or the Mionix Naos 3200. As it costs the same as the latter, and is less comfortable and adjustable, the Radon 5K won’t be finding its way onto our shopping list any time soon.
